Related to shaped rails is there.

  In recent years, as cultural standards have increased and civilization has developed, many of the multifunctional products that combine various functions into one have been produced by simplifying the complex of the past.

  It began with the desire of humans to try various things more conveniently and easily, reducing unnecessary work and waste of power, economic loss, etc., and closely related to our lives. This phenomenon also appears in some automobiles.

  For example, there is a demand for a multi-purpose vehicle that can carry luggage when carrying a lot of work, and can carry luggage with a family when traveling or having a picnic.

  Such multi-purpose vehicles are mainly passenger cars added with the function of a luggage vehicle, and unlike ordinary passenger cars, they are designed to be used by switching the interior space to various applications as needed. It is.

  As an example, in multi-purpose vehicles, seats that can be easily attached and removed are applied to the rear seats of the two-row or three-row seats as required, so that the cargo loading space and the boarding space can be easily switched. Yes.

  Such a detachable seat is a seat that is installed so that it can be easily separated from the vehicle body floor panel when a larger cargo loading space is required and the indoor space is to be expanded. On the other hand, a locking device for fixing or releasing the seat is installed and configured.

  Such a detachable seat is configured so that any user can easily remove or reattach the seat, and above all, the safety of the user must be considered.

  The inventor and the applicant of the present invention have applied for a patent for a locking device for a detachable seat for a vehicle in which a function that allows a user to visually confirm the locked state as well as a double fold function of the detachable seat is added. (See Patent Document 1).

  As shown in FIGS. 8 to 10, the locking device is provided at the front end and the rear end of the leg frame 10 below the seat and supports the leg frame 10 in a state of being coupled to the strikers 12, 13, and 15, respectively. Front end and rear end lock portions 100, 200 that have main brackets 110, 210 and are locked / released to the striker by the lock plates 112, 114, 212, and the front end lock portion 100 are locked to the strikers 12, 13 Thus, when the rear end lock part 200 is unlocked, the leg frame 10 includes a spring member 122 that provides an elastic restoring force so that the leg frame 10 can rotate in a double fold state around the front end lock part 100.

  In this locking device, the locking process of the front end locking part 100 is a two-stage locking process that is completed by the locking of the first locking plate 112 and the locking of the second locking plate 114, and the user can After the rear side is rotated downward, when the striker 15 is pushed so as to be inserted into the main bracket concave groove 212d of the rear end lock part 200, the rear end lock part 200 is locked.

  The above locking device can hold the strikers 12 and 13 to which the two lock plates 112 and 114 are fixed to the vehicle body, not only on the rear side of the seat but also on the front side of the seat, and can maintain a firm locked state.

  Further, according to this locking device, after the front end lock portion 100 is locked, the rear side of the seat is raised or the rear end lock portion 200 is unlocked, and then the elastic force of the spring member 122 is used to The seat is in a double-folded state with the side automatically lifted.

  When the seat is mounted, the rear end lock unit 200, which is finally locked, displays a locked or released state through an instruction hole of the leg cover 16 provided outside the leg frame 10 in conjunction with the rotation of the lock plate 212. And a state indicating unit for visually confirming the complete locking state of the locking device through the indicating bracket 220.

  On the other hand, this locking device has a structure in which the front and rear positions are fixed by locking with a striker fixed to the vehicle body, and FIG. 11 is a perspective view showing a striker applicable to this locking device. This will be described.

  As shown in FIG. 11, a plurality of strikers 12, 13, and 15 are installed by welding on the upper surface of a bracket 11 that is bolted to a vehicle body floor panel, and a striker cover 14 is fixedly installed on the upper side of the bracket 11. Each striker 12, 13, 15 has a structure in which a lateral portion penetrating the striker cover 14 and caught by the lock plate is positioned inside the striker cover 14.

  Here, two strikers 12 and 13 to which the front end lock portion (reference numeral 100 in FIG. 8) of the lock device is locked are arranged in front of the striker cover 14, and rear end lock portions ((FIG. 8 In FIG. 1, one striker 15 to which the reference numeral 200) is locked is located.

  Furthermore, in the case of a detachable seat, a slide rail is provided that allows the seat to be slid in the front-rear direction according to the physical condition of the seated person so that a comfortable posture can be maintained. The seat is seated and fixed.

  FIG. 12 is a side view of the seat schematically showing the position where the slide rail is installed in the detachable seat.

  As shown in FIG. 12, the slide rail 3 is composed of a fixed rail 3a fixed to the locking device 1 side at the lower end of the seat and a transfer rail 3b fixed to the cushion frame 2 side, and the transfer rail 3b is fixed. It moves in the front-rear direction while sliding on the rail 3a.

  Further, a lock system (not shown) is provided as means for restricting the movement of the transfer rail 3b, and when the handle portion 4 protruding forward of the seat is operated, the lock state of the lock system is released and the transfer is performed. The rail 3b can move back and forth.

  On the other hand, in the case of a multi-purpose vehicle, it is preferable to be able to adjust the position and mounting state of the seat more variously than a general passenger vehicle in order to further increase the utilization of the indoor space.

  For example, the seat front / rear position adjustment is usually required simply to maintain a comfortable posture based on the physical condition of the seated person, but in recent multi-purpose vehicles, the seat removal and In addition to the double fold, it is necessary to adjust the front / rear position of the seat with a larger moving amount (sliding amount).

  However, with the conventional slide rail, the amount of movement in the front-rear position is not so large. There are limitations.

  That is, in the case of a general seat, if the fixed rail is configured to be longer and fixed to the vehicle body floor panel, the amount of position movement can be increased. However, in the case of a detachable seat, the fixed rail 3a fixed to the lock device 1 side is lengthened. Therefore, there is a restriction on increasing the amount of movement in the front-rear position.

Conventionally, since the slide rail 3 is installed in the seat, the weight of the entire seat increases, and eventually, when the seat is removed from or attached to the vehicle, the heavy seat must be moved. However, there is a problem that it is not easy (the seat is not removed and is not easily mounted).
Korean Patent Application No. 2003-78837

  The present invention has been made to solve the above-described problems, and is provided with a striker and a moving means along a fixed rail that is relatively long and is mounted long on the vehicle body floor panel in the front-rear direction.

FIGS. 6, the cover is not shown, and only the inner configuration is shown. Reference numerals 422 a and 422 b are studs for fixing the cover (not shown in FIG. 4, 422) to the transfer rail 400. Each retaining ring is shown.

  First, the base bracket 411 is mounted on the mounting portion of the lock assembly 410, that is, the bottom surface of the central portion of the transfer rail 400. The base bracket 411 protrudes so that a space is formed between the transfer rail 400 and the bottom surface. It is bent and formed into a shape structure, and is fastened and fixed to the bottom surface of the transfer rail 400 by bolts (not shown) inserted into the fastening holes 412a at both ends.

  In addition, on the upper surface of the base bracket 411, guide slots 411b for guiding a push plate 418, which will be described later, back and forth are formed on both the front and rear sides (the left side and the right side in the drawing). .

  A base block 412 is fastened and fixed to the bottom surface of the transfer rail 400 by a bolt (not shown) inserted into the fastening hole 412a in one side of the space between the central portion of the base bracket 411 and the bottom surface of the transfer rail 400. In the remaining space, a lock plate 413 that is locked to the lock hole 304 of the fixed rail 300 is provided.

  The lock plate 413 has a plurality of teeth 413 a formed at equal intervals on one side and locked to the lock holes 304 of the fixed rail 300, and the side holes in which the teeth 413 a are formed on the side wall of the transfer rail 400. A lock hole 304 of the fixed rail 300 is locked or unlocked through 405.

  Here, when the teeth 413a of the lock plate 413 are inserted into the lock holes 304 of the outer fixed rail 300, the lock is made between the fixed rail 300 and the transfer rail 400. In the unlocked state, the teeth 413a of the lock plate 413 are The lock between the two rails 300 and 400 is released through the lock hole 304 of the fixed rail 300.

  During the unlocking operation of the lock assembly 410, the lock plate 413 receives a rotational force of a link 414, which will be described later, and is pulled and moved inward of the transfer rail 400 so that the teeth 413a of the lock plate are locked to the fixed rail 300. The hole 304 can be pulled out.

  In addition, guide members 423 having a plurality of holes 422a through which the teeth 413a of the lock plate pass are installed inside the side holes 405 of the transfer rail 400. The holes 423a of the guide members 423 When the lock plate 413 is moved laterally, the lock plate teeth 413a are guided.

  That is, even when the lock plate 413 is mounted, a part of the tip of each lock plate tooth 413a is inserted into the corresponding hole 423a of the guide member 423 even in the unlocked state. The lock plate teeth 413 a protrude longer from the outer side of the hole 423 a of the guide member 423 and are inserted into the lock hole 304 of the fixed rail 300.

  On the other hand, the link 414 is positioned on the upper side of the lock plate 413 and has one end hinged to the lock plate 413 and the other end integrated with the lower end of the rotation shaft 416 of the central lever 415. And is rotated by the rotation of the central lever 415 and serves to pull the lock plate 413 inward of the transfer rail 400 or to push it outward.

  The central lever 415 is integrally fixed to the upper end of the rotating shaft 416 penetrating the base bracket 411 up and down so that the push plate 418 is rotated by an operation of pushing the operating pin 415a on the upper side of the base bracket 411. It has become.

  Further, the central lever 415 is formed symmetrically, and its central portion is fitted and fixed to the upper end of the rotating shaft 416, and as shown in FIG. 7a, both end sides are on both front and rear (left and right in the drawing). The two push plates 418 are disposed obliquely so as to be directed to the front end sides of the two push plates 418, and are installed in a substantially diagonal direction with respect to the base bracket 411.

  In addition, an operating pin 415a protrudes from both ends of the central lever 415. The operating pin 415a is a pin that is pushed by the tip of one push plate 418 during the unlocking operation. When the push plate 418 pushes the operating pin 415 a, the center lever 415 rotates and the rotation shaft 416 and the link 414 below the base bracket 411 rotate so that the lock plate 413 moves inward of the transfer rail 400. Being pulled.

  A return spring 417 that provides an elastic restoring force between the base bracket 411 and the central lever 415 is installed on the rotation shaft 416 of the central lever 415. The return spring 417 makes the central lever 415 elastically. It is designed to rotate.

  Here, the upper end of the return spring 417 is fixed to the base bracket 411, and the lower end on the opposite side is fixed to a fixing protrusion 415 b protruding from the lower surface of the central lever 415.

  The spring force of the return spring 417 acts so that the central lever 415 can rotate counterclockwise on the drawing.

  Here, when the central lever 415 overcomes the spring force of the return spring 417 and rotates clockwise in the drawing, the lock plate 413 is moved inward of the transfer rail 400 by the rotation shaft 416 and the link 414 below the base bracket. When the central lever 415 is rotated counterclockwise by the elastic restoring force of the return spring 417 when the lock with the fixed rail 300 is released and the lock lever 415 is rotated counterclockwise, the lock plate 413 is attached to the transfer rail 400 by the rotation shaft 416 and the link 414. The fixed rail 300 is locked while being pushed outward.

  When the lock assembly 410 is not operated by an external force, the spring force of the return spring 417 acts in the counterclockwise direction of the central lever 415, so that the lock assembly is always locked.

  The push plate 418 is integrally coupled to the upper operation lever 419 and is slid forward and backward along the guide slot 411b on the upper surface of the base bracket 411. When the operation lever 419 is pressed, The lever 415 moves together, and the tip of the lever 415 pushes the operating pin 415a on one side of the central lever 415.

  The actuating lever 419 is fastened by a lower push plate 418 and a bolt 421 so as to move forward and backward integrally with the push plate 418, and a pressing end 514 a of an unlocking operation means 500 described later is located outside the cover 422. It moves to the center lever 415 side by the operation | movement which presses to inner side from.

  The bolt 421 that vertically penetrates the operating lever 419 and the push plate 418 and is fastened is guided in a state where the lower end portion is inserted into the guide slot 411b of the base bracket 411 during the forward / reverse operation. The lever 419 and the push plate 418 can be guided along the guide slot 411b.

  Further, the operation lever 419 and the push plate 418 have the same structure, and are symmetrically installed one on each of the front and rear sides (left and right sides in the drawing) around the rotation shaft 416 of the center lever 415. Even if any one of the operating levers is pressed, the central lever 415 is rotated in the same direction.

  The pressing end 514a of the unlocking operation means 500 pushes the left end in the case of the operating lever 419 positioned on the left side in the drawing, and presses the right end in the case of the operating lever positioned on the right side.

  Of course, in a state where both the operating levers 419 are not pressed, the operating pin 415a of the central lever 415 receiving the spring force of the return spring 417 is brought into contact with the tip of the push plate 418.

  On the other hand, this configuration is located inside the cover 422 that is fixedly mounted on the transfer rail 400, but the cover 422 has two front and rear studs that penetrate the cover 422 and the transfer rail 400 laterally. The position is fixed by 422a.

  That is, in a state in which the cover 422 is placed inside the transfer rail 400 so as to cover the entire internal structure, each stud 422a is laterally inserted into the fastening holes 406, 422d on both side walls of the transfer rail 400 and both side walls of the cover 422. After that, the fixing ring 422b is fitted into the end protruding to the opposite side, and the stud 422a is fixed so as not to come off.

  Openings 422c are formed on both the front and rear sides of the upper portion of the cover 422, and a part of the two operating levers 419 on both the front and rear sides is exposed to the outside through the openings 422c. Both side ends of 418 are engaged with the inner end of the opening 422 c of the cover 422 so that the operating lever 419 does not come out of the cover 422.

  On the other hand, the long slide rail according to the present invention includes unlocking operation means 500 for operating the lock assembly 410 so as to unlock between the two rails 300, 400. Will be described with reference to FIG.

  The unlocking operation means 500 plays a role of releasing the lock state of the lock assembly 410 by pressing the operation lever 419 of the lock assembly 410 installed on the transfer rail 400 toward the inside of the cover 422 by the operation of the user.

  The unlocking operation means 500 is installed in the locking device 1 at the lower end of the seat, and is installed in the front portion of the seat where the front end locking portion 100 is provided, more specifically, in the front portion of the leg frame 100. Is done.

  Further, in the present invention, the long slide rail is installed symmetrically on the vehicle body floor panel below the seat as the same structure, and the unlocking operation means 500 is also the same as the leg frame 10 on the left and right sides of the seat. Is constructed symmetrically as a simple structure.

  First, an operation lever 511 that is installed to be elastically rotatable inside the leg frame 10, and a link device that presses the operation lever 419 of the lock assembly 410 inward of the cover 422 in conjunction with the rotation operation of the operation lever 511. 513, 514.

  Here, the operation lever 419 is formed with a long handle portion 511a on the front side with respect to the rotation center set inside the leg frame 10, and a link device is connected and installed on the opposite side.

  The handle portion 511a is provided so that the front end portion projects forward from the lower side of the seat so that the lock assembly 410 of the left and right two transfer rails 400 of the seat can be operated simultaneously. It is provided in a “-” shape, and has a structure in which both left and right operation levers 511 are connected to each other.

  The operation lever 511 has a structure that is elastically rotated by a return spring 512 connected to the leg frame 10 on one side opposite to the handle portion 511a. The return spring 512 has an operation lever 511. Acts to pull one side of the operating lever so as to elastically rotate counterclockwise on the drawing.

  Next, the link device is installed on the opposite side of the handle portion 511a so that one end of the link lever 511 is connected to the end of the operation lever 511, and is rotatably installed inside the leg frame 10. The second link 513 is connected to the other end of the link 513, and the other end is a second link 514 including a pressing end 514 a that presses the operating lever 511.

  Here, the first link 513 moves forward and backward during the rotating operation of the operation lever 511, and serves to rotate the second link 514 by pulling or pushing out.

  Hereinafter, the front and rear movement states of the seat according to the present invention will be described with reference to the drawings.

  First, in order to move the seat in a state where the front and rear positions are fixed, the lock assembly 410 must be unlocked.

  Therefore, when the user grasps the operation lever handle portion 511a on the front side of the seat and pulls it upward, the pulling force causes the operation lever 511 to overcome the spring force of the return spring 512, and the clockwise direction on the drawing centering on the rotation center. As a result, the first link 513 is pulled forward of the seat, and the second link 514 is rotated counterclockwise on the drawing.

  As a result, the pressing end 514a at the lower end of the second link 514 presses the operating lever 419 toward the rear side of the seat, that is, toward the inside of the cover (see FIG. 1).

  Thus, when the operation lever 419 is pressed by the operation of the unlocking operation means 500, the lock state of the lock assembly 410 that has locked between the fixed rail 300 and the transfer rail 400 is released.

  Here, since the handle portion 511a connects the two operation levers 511 on the left and right sides of the seat, the operation levers 419 on both the left and right sides are simultaneously pressed. At the same time, the lock is released and the seat can be moved back and forth.

  Referring to FIGS. 7A and 7B, the process of unlocking each lock assembly will be described. When the front operation lever 419 is pushed, the push plate 418 moves to the center lever 415 side. Eventually, the tip of the push plate 418 pushes the operating pin 415a of the central lever 415, and the central lever 415 overcomes the spring force of the return spring 417 and rotates clockwise in the drawing.

  Further, when the central lever 415 rotates, the link 414 rotates clockwise around the rotation shaft 416 of the central lever 415 at the lower side of the base bracket 411, so that the lock plate 413 moves inward of the transfer rail 400. When the teeth 413a of the lock plate 413 are pulled out of the lock holes 304 of the fixed rail 300 by being pulled, the lock between the two rails 300 and 300 is released.

  As described above, in a state where the lock between the two rails is released, the user moves the seat back and forth to adjust the position, and then releases the handle portion 511a again. Then, the operation lever 511 is moved to the spring 512. The first link 513 is pushed while elastically rotating in the opposite direction by the restoring force, and the second link 514 is rotated in the opposite direction while the first link 513 is pushed, so that the pressing state of the operating lever 419 is released.

  When the pressing state of the operating lever 419 is released in this way, the central lever 415 is elastically rotated counterclockwise as shown in FIG. 7b by the elastic restoring force of the return spring 417 mounted on the rotating shaft 416 of the central lever 415. Then, the operating lever 419 is pushed out again through the operating pin 415a and the push plate 418.

  Further, the lower link 414 of the base bracket 411 rotates counterclockwise around the central lever rotation shaft 416 while the central lever 415 is elastically rotated, and at this time, the link 414 pushes the lock plate 413 to the side. As a result, the lock plate teeth 413a are fitted into the respective lock holes 304 of the fixed rail 300 to lock the two rails 300 and 400, and the front and rear positions of the seat are fixed again.

  On the other hand, in the removable seat in FIG. 1, the front end lock part 100 of the locking device 1 is locked with two strikers 401 positioned on the front side in the transfer rail 400, and the rear end lock part 200 is located in the transfer rail. Among the two strikers 402 on the rear side, the rear striker is locked.

  According to the rail of the present invention, two strikers 401 and 402 are installed at symmetrical positions around the lock assembly 410 located at the center of the transfer rail 400, and the central lever 415 is rotated within the lock assembly 410. Since the operation lever 419 and the push plate 418 for operating each are installed one by one around the center lever 415, the seat can be mounted in the direction opposite to the longitudinal direction of the vehicle body. When the handle portion 511a positioned at the position is pulled, the unlocking operation of the lock assembly 410 is performed in the same manner as when the seat is mounted in the forward direction.

  That is, when the seat portion 511 on the front side of the seat is pulled with the seat mounted in the reverse direction, the unlocking operation means 500 operates in the same manner, and the operating lever located behind the lock assembly 410 in the transfer rail 400. 419 is pushed to the front side of the seat, and at this time, the central lever 415 is rotated in the same direction while the operation lever 419 on the rear side is pushed, so that the link 414 on the lower side of the base bracket 411 is eventually obtained. Thus, the lock plate 413 is pulled to release the lock.

  Of course, although not shown in the drawings, when the seat is mounted in the reverse direction, two strikers 402 in which the front end lock portion 100 of the locking device 1 is positioned on the rear side in the transfer rail 400 is opposite to the case of mounting in the forward direction. The rear end lock portion 200 is locked with the front striker among the two strikers 401 on the front side in the transfer rail.
